    • 2004, K.S. Cheng, Gustavo E. Romero (editors), Cosmic Gamma-Ray Sources, page 191, figure caption,
      The expected gamma-ray spectrum of the Soft Gamma-ray Repeater SGR 1900+14 for various inclination angles.
    • 2004, Quang Ho-Kim, Narendra Kumar Kumar, Harry C. S. Lam, Invitation to Contemporary Physics, 2nd Edition, page 308,
      Other missing neutron stars might be the unpredictable soft gamma-ray repeaters (SGRs), the recurrent soft X-ray transients discovered in the 1980s. Although there are only a few examples known at present, SGRs have attracted a lot of attention lately because of their unique characteristics.
    • 2008, W. Becker, F, Haberl, J Trümper, 14: Pulsars and Isolated Neutron Stars, Joachim E. Trümper, Günther Hasinger (editors), The Universe in X-Rays, page 193,
      The radio-silent neutron stars include anomalous X-ray pulsars (AXPs), soft gamma-ray repeaters (SGRs), and “quiescent” neutron star candidates in SNRs. There is growing evidence that AXPs and SGRs are indeed magnetars (see [109] for a review).
